AM-013 / 014 / 015 BEU™ Battery Extension Unit - Black



The Battery Extension Unit (BEU) is designed especially for the Ares Amoeba AM-013/ AM-014 and AM-015 Honey Badger series used to connect a larger battery to the gun while keeping it external to the gun's body. This allows players to use higher-capacity batteries for longer gameplay without compromising the aesthetics or functionality of the airsoft gun.

Ready For Battle


Fast Installation and with Ease

By offering additional spacing inside the compartment, the Battery Extension Unit Unit (BEU™) is designed specifically to relieve all stresses on the rifles components such as the MOSFET and to prevent the bending of electrical cables to protect it throughout, increasing its durability.

Light & Strong Contruction

Made of strong, flexible nylon that is resistant to BB impact and rough handling. With the extra air space inside the compartment, the BEU™ will protect the MOSFET, fuse, wires, and battery from overheating over time. Likewise, we wanted to minimize the prospect of denting the battery's surface from the cramped spacing.
